Abstract (en)

[origin: EP4061053A1] The present application discloses a beam tracking method and device, a base station, and a computer readable storage medium. The beam tracking method comprises: establishing an adjacency list according to initial correlations between beams; determining, according to the adjacency list, a first type of related beams having a correlation to a current optimal beam that is greater than a first threshold; scanning the current optimal beam and the first type of related beams; performing, starting from the first type of related beams, cyclic scanning on beams in the adjacency list; determining, according to received signal quality of the scanned beams fed back by a receiving party, a correlation between any two of the scanned beams, and updating the adjacency list; and determining, according to the updated adjacency list, whether beam deviation has occurred, and re-determining the current optimal beam.
